Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mashed potatoes
Provides the bulk and soft body that holds the balls together.
Codfish
Supplies the main flavor and protein, giving the balls their savory character.
Eggs
Bind the mixture so the balls hold their shape while frying.
Butter
Adds richness and moisture to the mixture.
Lard
Conducts heat for frying and gives the outside a crisp, golden browning.

The step that matters

Frying in hot lard. If the lard is not hot enough, the balls absorb grease and turn heavy and greasy before the outside browns. Enough heat sets the surface quickly, forming a crust that keeps the inside moist and the oil out.

Swap the potato

How well each one fits the dish's main ingredients (butter, egg):

  1. Asparagusfits better
  2. Chivefits better
  3. Leekfits about as well
  4. Potatothe original

Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
